    Project Details


    The work is a part of a cooperation between European metrology laboratories under the auspices of EUROMET.
    An automatic method has been developed to calibrate audiometric headphones in the frequency range up to 20 kHz. A number of high frequency headphones have been calibrated and are now circulating among the participating laboratories for calibration. Similarly three standard type audiometric headphones have been received from NPL and returned after calibration. Comparison and reporting of the results is expected in 1997.
